Hawkeye is criminally under-used in the MCU, which is a shame given that Renner is probably the best actor amongst all of the Avengers, but I can't see him being given his own Netflix series.

And on Agents of SHIELD, though I watch it I can't profess to be a big fan of it. I always thought building a television show around Phil Coulsen was a pretty bad idea. Clark Gregg is a good character actor but I don't think he's a strong (or convincing) enough presence to carry a show on his own. I understand why they green-lit the series, I watch it because... it helps to pass the time when I have nothing better to do, but I wouldn't be deathly disappointed if it were cancelled. It doesn't really add much to the MCU or say anything particularly worthwhile.
